When people develop myelodysplastic neoplasms (MDS), the healthy maturation of blood cells is impaired. Severe forms, known as higher-risk MDS, are characterized by rapid progression, severe symptoms and often a transition to acute leukemia. Patients for whom potentially curative or intensive treatments, such as stem cell transplantation or high-dose chemotherapy, are not suitable, have very few alternative treatment options.

Scientists have successfully trapped atoms of krypton (Kr), a noble gas, inside a carbon nanotube to form a one-dimensional gas. Scientists used advanced transmission electron microscopy (TEM) methods to capture the moment when Kr atoms joined together, one by one, inside a 'nano test tube' container with diameter half a million times smaller than the width of a human hair.

A team of scientists has demonstrated that communication among memory-coding neurons -- nerve cells in the brain responsible for maintaining working memory -- is disrupted with aging and that this can begin in middle age.
